The present invention relates to typographical machines and moreespecially to line casting machines of the general class shown anddescribed in U. S. Letters Patent $36,532, granted September 16, 1890,to O. Mergenthaler, wherein molten metal is forced into a slotted moldagainst a composed line of character-bearing matrices to produce aprinting slug or type bar which is subsequent y removed from the mold byan ejector which is advanced against the rear edge f the sing and pushesit edgewise from the mold into a galley.

In t e operation of machines of this class, it frequently becomesnecessary to vary the length of the mold slot in order to produce slugsof different lengths to accord with the measure of the body or column tobe printed. Machines of this class, in practice, are provided with moldwheel or carrier on which a plurality of molds are mounted so that oneor another thereof may be broughtinto use, and the different molds mayhave casting slots which differ in length and height so that slugs ofseveral different sizes, according to the requirements of the work inhand, can be cast by merely bringing one or another of the molds intoactive position. However, the requirements of the various classes ofcompositicn will not always enable a sufficient assortment of molds ofdifferent sizes to be always present on the mold carrier, so thatfrequently it becomes necessary to remove one or more of the molds fromthe mold carrier and re place it r them with another mold or. othermolds, or one or more of the moldsmay be partially dissembled andprovided with a liner of a difierent size, such liner being the usualchangeable mold member which determines the length of the casting slottherein.

llerei'ioforc, such bringing into operative position of a differentmoldalready mounted in the mac he or such changes in the molds or the linersthereof, has required the opera-'- tor perform subsequent operationwhere- J 1 a an 1CLO1 olaue of tie pro-per widthto pass through theslotof the selected or altered mold and to push out the slug cast therein,would be set manually into operative )osition and the erformance of thise'ector blade selecting or adjusting operation has dependent upon thethoughtfulness or attentron of the operator. In consequence, itfrequently happens that the operator, through.

carelessness or inattention, forgets to make t ie e ector blade settmgor adjustment to 'accord with the selected or altered mold, and

upon starting the machine into operation, 7 i

such has resulted in the presentation of an improper ejector blade tothe mold when the latter reaches the ejecting position, and if suchblade is too long to enter the mold slot, such ejector blade wouldj amagainst the back of the mold liner and, in many cases, cause ser1- ousdamage.

v it-tempts have been'made to provide safety means to protect themachine from damage due to failure of the operator to bring into use anejector blade of the proper width to conform with the changeo or alteredmold,

but such safety means-as have been proposed 7 have been found deficientor otherwise unsatisfactory for practical use, due to the mechanicalintricacies thereof 'or to their failure to provide afull measure ofprotection to the machine.

- T he primary obj ectof the present invention is to provide an improvedmechanism which will overcome the above mentioned deficiencies and whichwill serve effectively not only as a safety means to protect the moldsand linersiand other parts of'the machine from damage but which willalso render the selection of the required ejector-blade or the propersetting of the ejectormechanism automatic each time a mold having a slotof different length er a mold liner of differentlength is brought intouse.

A more particular object of the invention is to provide an automaticejector se setting mechanism which is compelled to come into operationeach time the operator lecting v rotates the mold wheel, which moldwheel rotation always precedes the bringing of a different mold thereoninto use or the introduction of a new mold on the mold wheel or changesin the length of the liners of the molds thereon. Y.

A further object of the invention is to provide ejector selecting orsetting mechanism which is so constructed and arranged that failure tooperate it in the proper'manner will prevent operation of the ejectoruntil the correct operation of the ejector selecting or settingmechanism has been performed.

To these and other ends, the invention consists in certain improvementsand combinations and arrangements of parts all as will be hereinaftermore fully described, the features of novelty being pointed outparticularly in the claims at the end of the specification.

The preferred embodiment of the invention is shown in the presentinstance and will be hereinafter described in detail, but it is to beunderstood that the invention is not restricted to the particularconstruction shown, since equivalent constructions are contemplated andsuch will be included within the scope of the claims. In' the presentinstance, the invention is shown and will be hereinafter or settingmechadisconnected describech'for example, as applied to multiple bladeejector mechanism of the general form shown and described in my prior U.S. Patother forms of multiple "lads ejectors such as those now in use.

. In the present instance, 1 represents the usual mold slide of a linecasting machine of the general class hereinbefore referred to, such moldslide being mounted for example in the usual way and having the ejectormechanism mounted therein,the mold slide having as usual a hub 2projecting laterally there from and rotatably supporting the usual moldwheel 6, 3 represents theusual mold gear arm forming part of the mainframe of the machine, it being supported toward its forward end by theusual. upright post or bracket 4, and 5 represents a cross arm orbrace,'forming part of the main frame of the machine. The mold wheel 6,in machines of this class, is usually constructed and arranged to carryfour molds 6, the mold wheel and the molds thereon being constructed andarranged for example as shown generally in U. S. Letters Patent No.758,103, granted April 26,1904, to W. H. mounted on a shaft 8 supportedin the upright post or bracket 4 meshes witl the peripheral gear teethon the mold wheel and serves to rotate the latter, the rear end of theshaft 8 being driven at appropriate times and to Randall. A pinion 7 theproper extents by the driving mechanism of the machine to carry the moldon the mold wheel which is in use from normal ejecting position tocasting position and from the latter position to normal ejectingposition, means being usually provided in machines of this class forholding the mold wheel against turning inadvertently out of proper timedrelation with the machine during the intervals between its rotatingmovements, and the pinion 7 serves as means by which the mold wheel maybe rotated independently of its operating shaft 8 in order to bring adiiferent mold on the mold wheel into operative position, it beingcommon in machines of this class to provide a locking pin on the pinionoperating shaft 8 and to provide the rear face of the pinion 7 with arecess in which such pin may engage to normally connect the pin ion toits operating shaft, the pinion being movable axially on its'operatingshaft to disengage it from the locking pin and rotatable while sodisengaged wh reby it may rotate the mold wheel. into thedesiredposition.

According to the present invention. the pinion 7 is rotatable on itsdrivmg shaft 8 but is held from longitudinal movement thereon, and i isoperatively connected and with respect to the shaft 8 by a pin 9projecting forwardly from a clutch collar 10, the latter being splinedon the shaft 8 so that it will always rotate therewith but may moveaxially thereon to engage and disch nge the pin 9 with respect to arecess or hole 11 formed in the rear face of the pinion 7. Normally, theclutch collar 10 will be in forward position with the pin 9 thereon inengagementwith the recess or hole 11 in the pinion '7 so that the latterwill be driven by the shaft 8 and will be held against rotationindependently thereof, but when the'cluich collar 10 is shifted.rearwardly, the pin 9 thereon will be withdrawn from the recess or hole11, thereby disconnecting the pinion 7 from the shaft 8 and the pinionwill then be free for independent rotation to bring any desired mold onthe mold wheel into operative position. The means shown in Figs. 1, 2. 3and 8 for controlling the driving connection between the pinion nd theshaft 8 comprises a clutch shifting arm 12 having a yoke hereon providedwith oppositely arl5) ranged pins 1% which engage in a circumferentialgroove 15 in the clutch collar 10, the arm 12 being' guided forreciprocation longitudinally of the shaft 8 by abracket plate 16 securedby screws or other suitable means to the upright post or oraclret 4. Thearm 12 is nvotally connected to the upper end of a vertical lever 17which latter is pinned or otherwise fixed at its lower end to one end ofa horizontal shaft 18 rotatably mounted in the cross arm 5 of themachine frame, the lever 1'7 being constantly urged forward by a coilspring 19 which encircles the shaft 18, one end of the spring beingfixed to the machine frame and its other end acting on the lever 17. Theother end of the shaft 18, as shown in Fig. 3, has vertical. lever 20pinned or otherwise fixed tlnireto and the forward face of this lever isopposite to and in a position to contact with the rear end of anadjustable setscrew 21. the latter being carried in a suitable bracketwhich is pinned or otherwise fixed to a shaft-23. the latter extendinglo gitudinallvfrom the front to the rear of the mold slide along orbeneath its lower edge and being guided to slide longitudinally inbearings 89 and 10 formed in a bracketll which is fixed by screws orotherto the mold slide 1. According to this construction, the spring 19normally acts to swing; the lever 17 also the arm 12 forwardly, ti erebyholding the clutch collar 10 in its forward position and the pin 9thereon in engagement with the recess 11in thepinion 7 so that thelatter will be normally locked to its driving shaft 8, and the 3l1'1l9117 cannot be turned independently of the shaft 8 until the clutch collar10 has been shifted rearwaroly into the position shown in Fig. 2, as byrearward movement of the set screw 21 to carry it into engagement withthe lever2O and to swing the latter rearwardly from its normal positionshown in Fig. 3. The means by which the set screw 21 is thus shiftedwill b-efore referred to. For the purposes of the pr sent invention. itis deemed SLllllClQlll] to describe it as comprising an ejector slide'24 mounted to reciprocate between upper and lower guide rails 25 and 26formed on the molc. slide 1 and 8X aiding longitudinally of the moldslide so that the ejector slide may reciprocate forwardly and rearwardlyunder the action ofth-e connecting link 27 which reaches toward the rearof the machine where it is acted upon at appropriate times by the maindriving cams in the well-known manner. A master blade 28 is secured toone side of the ejector slide 24 and extends forwardly ther om it.-having hapedextension 29 pro ecting forwa dly from its forward edgewhich serves as a key to engage in a correspondingly shaped recess inthe rear edge of any one of of ejector blades 30 when the master blaoe28 is in register or alignment with'such ejector blades. The ejectorblades 30 are contained within a magazine or blade box 31 which ismovable transve 'sely of the path of movement of the master blade 28 tobring any one of the ejector blades into register with such masterblade,the magazine or blane hon being; mounted for this purpose between upperand lower bars 82 which are guided to slide longitudinally in the moldslide 1 and are connected at their rear ends by a yoke or cross bar 33having; a lug: 3d projecting ally therefrom and by which the bars 32 arereciprocated. The sides of the bars toward the upper and lower edges ofthe blade box 31 are formed ith obliquely extending ribs 85,.and theserib cr ase correspondinf obliquely e7;- tc. grooves 37 in the upper andlower edges of the bla box. The lug or projection 34 for shifting: thebars is arranged to be engaged by an arm '36 which is pinned orotherwise fixed on the shaft 23 so that itwill move forwardly or r-earwlly therewith. It

2 will sh ft forwill be seen that the a, wardly or rearwardly wi iin themold slide 1 in accordance with corresoonding movements oia zes 3G inthe blade box are of different .mold slide and to.

lengths in the molds that may be used, and

the recesses in the rear edges of the ejectorblades are all on a commonlevel so that any one of them may receive the key or projection 29 onthe master blade, according to the lateral position into which the bladeboX is shifted. It will be understoodthat the master blade 28 iswithdrawn to its rear position when the blade box is shifted to bring aselected ejector blade therein into use. A guide post 38having a portionthereon of a shape co responding within the recesses 1n the rear edgesof the ejector blades so that it may enter such recesses is shownimmediately beside the master blade 28, this guide post insuringexact-registration of the recess of any selected ejector blade with thekey or extens on 29 on the master blade. In Fig. 8, the master blade isshown in operative engagement with the smallest or narrowest ejecto:blade, and the ejector slide 24 is shown in its forwardly advancedposition, thus illustrating the manner, in which an ejector blade ismoved forwardly to extend through the cavity of the mold.

Forward or rearward movement of the shaft 23 to shift the blade box 31to bring one or another of the ejector blades 30 into register andoperative relationship with the master blade 28 is accomplished, asshown in F ig. 8, by an operating lever 42 arranged at the front of themachine, this lever being pivoted intermediately of its l ngth at 43 toan extension 44 of the bearing bracket 41, this operating lever beingconnected to the forward end of the shaft 23 by a link 45 which is'pivotally connected to the shaft 23 and to said operating lever. Theoperating lever 42 normally occupies the full line position shown inFig. 301 the position shown in Fig. 8 but may be swung forwardly intothe dotted line position shown in'Fig. 3. When the lever 42 is in itsnormal position, the set screw 21 will be in its forward position beyondthe lever 20 and hence the pinion 7 will be locked by the clutch collar10 to its driving shaft 8, so that the mold wheel 6 cannot be rotated tobring a different mold thereon into operative position unless the clutchcollar 10 is shifted rearwardly to withdraw the locking pin 9 thereonfrom the recess 11 in the mold turning pinion. To accomplish this, theoperating lever 42 is swung forwardly about its pivot 43 from the fullline position to the dotted line position shown in Fig. 3, such movementof the oper ating lever causing the shaft 23 to be moved rearwardly sothat the screw 21 carried thereby, during the latter part of the forwardswing of the operating lever, will contact with the front face of theupper end of the vertical lever and will then swing the lever 20rearwardly; The rearward of the upper end of the lever 20, as will beseen from Fig. 2, will rotate-the shaft 18 pin 9 on the clutch collarswing against the action of the spring 19 and in a direction to swingthe lever 17 rearwardly,

thereby drawing the arm 12 and the clutch collar 10 rearwardly and.thereby withdrawing the pin 9 on the clutch collar from the recess 11 inthe pinion 7, and the latter will then be unlocked or free to turn onthe shaft 8 and it may be revolved to rotate the mold wheel to bring anydesired mold thereon into operative position or to bring a mold thereonfrom normal ejecting position to the upper horizontal position where itmay be replaced by another mold or may be altered to contain a linerofdiiferent length. In the construction shown in Figs. 2, 3 and 8, theoperating lever 42, when pulled forwardly to its full extent, as shownby the dotted lines in Fig. 2, will lock he shaft 23 against forward orreturn movement since the link in 0011-, junction with the end of thelever 42 to which it is pivoted forms a toggle the middle pivot of whichpasses beyond the center line between the pivot 43 and the pivot bywhich the link 45 is connected to the forward end of the shaft 23, sothat the pinion 7 will be thus maintained in unlocked relation with itsdriving shaft 8 while the mold wheel is being turned, and after thedesired mold has been brought into operative position by rotation of themold wheel, or the operation of mounting a new mold on' the mold wheelor of inserting a liner of different length in a mold'on the mold wheel,which latter operations also involve rotating the mold wheel to carrythe mold to be replaced or altered from the normalejecting position tocasting position and to return such mold to its normal ejectingposition, the pinion 7 is again connected to its driving shaft 8 byproperly aligning the recess 11 in the pinion with the 10 and thenswinging the operating lever 42 back to its normal rearward position,the consequent forward movement of the shaft 23 causing the set screw 21to recede from the lever 20 so that the latter and also the lever 17 arefree to swing forwardly under the action of the spring 19, the forwardswing of the lever 17 shiftingthe clutch collar 10 forwardly and therebycausing the pin 9 thereon to enter the recess 11 in the pinion.

Machines of this class are usually provided with a control or startinghandle 46 which, as shown in Fig. 8, is pivoted to the machine frame at46 and is connected by a toggle 46 to bars 146, the rear ends of thelatter engaging a clutch lever 47 pivoted on the machine frame andcontrolling themain drivring clutch of the machine so that when thehandle 46 is pushed rearwardly the main driving clutch is disengaged andwhen said handle is pulled forwardly, the bars 146 are drawn forwardlyand, the main driving clutch is engaged to start the machine into.operation. Means is provided by the present inventionfor preventingstarting; of the machine unless the operating lever d2 for setting theeject-or mechanism has been returned to its normal position. It will beobvious that should the operator neglect to return the operating handle1.2 to normal pr on so as to effect reengagement of the pi 9 in therecess 1101" the pinion 7 before starting the machine by pulling thecontrol handle -6 forw rdly, the machine would operate l isual wayexcept that the mold wheel, n on is driven by power transmitted itthrough the usual pinion shaft 8, would be disconnected. Under suchconditions, the mold wheel would to bring selected mold into position infront of the usual metal pot and to align the matrices for casting, butthe mold at the top of the mold wheel, which would u W be of impropersize in leng h. or hr 111- of its slot or otherwise,

would be in position, so that serious damage might occur to parts of themachine, or a metal squirt might result and endanger the operator. Toprevent such an occurrence, a depending arm 43 is pinned or otherwisefixed to the forward end of the reciprocatory shaft 23. its lower endoverlying the forward ends of the rods 1&6, By this arrange-- ment, whenthe operating handle 42 is pulled forward to move the shaft'23rearwardly to disengage the pin 9 from the recess 11 in the pinion 7,the overlying arm 48 will block the rods 146 against any inadvertentforward movement of the machine control handle 16, and hence the maindriving clutch of the machine cannot be thrown into engagement to themachine until the operating handle 42 has been pushed back to normalposition.

The present invention provides means for automatically selecting theproper ejector blade 30 to correspond with the length of the ot in themold which is brought into opposition, and such means will now Pdescribed.

as top of the mold slide 1 carries a jcr forwardly. A projection 58:Yardly from the arm 36into a poion engage stop pin 59 which is fixed toand projects laterally from the selector fine to control latter in itsforward not be rotated bracket 49 which is pivoted on said slide by ngacting to constantly urge the se movement under the tension of thespring 54. The upper end of the arm 36 has a horizontal and forwardextension 60 and the forward end of this extension is provided with aseries of steps 61 which extend in a'-' row obliquely to the length ofthe extension 60 r which the lug 341 on the yoke 33 projects.

In consequence, rearward movement. of the shaft 23 and the arm 36 willshift the'lug 3 1 from a position in engagement with the rear end of theaperture 65, as shown for example in Figs. 5 and 6, to a position inengagement with the forward end of this aperture as shown in Fig. 1, andowlng to theconnection of the lug 3 1 through-the yoke 33' and slidvable bars 32 and-the oblique ribs 35 thereonwith the blade box 31, thelatter will be moved into one of its extreme lateral'positions so thatone or another of theend ejector blades therein, preferably thewide'stone within the blade box 31, will be in register with the masterblade 28. The arm 36 carries a roller 136 at its upper end, and thebracket 49fis formed with a track or cam surface 13?, this roller andcam surface being so arranged that as the arm 36 shifts rearwardly from.the position shown in Fig. 5 to that shown in Fig. 1, the roller 136willengage the cam sur face 137 and will act thereon to swing thebracket 49 upwardly from its forwardly and.

downwardly inclined position shown in Fig 5 to its upper, approximatelyhorizontal position shown in Fig. 1. It will be under.- stood, from whathas been already stated, that the forward movement of the operatinglever 42 which shifts the arm 36into the rear position shown in Fig. 1,disengages the driving pin 9 from the recess 11 in the mold turningpinion 7, so that the mold wheel may then be rotated to bring anothermold into operative or active position. After the de- 7 sired mold hasbeen brought to vertical position' in front of the ejectonwhich may beaccomplished by turning the thenunloclred pinion 7, the return of theoperating lever 42 to normal position, which must take place aspreviously stated, to permit startingof the machine, moves the shaft 23and the arm 36 thereon-forwardly, and during the initial part of suchforward movementofthe-arm.

which moves for 36, the roller 136 thereon, wardly with the arm 36, willdisengage from the cam. track 137 on the pivot-ed bracket 49 so that thelatter will be no longer supported in its upper or horizontal positionbut will tilt downwardly about its pivot 50, under the influence ofgravity so that it assumes a posi tion such as that shown for example inFig. 4. Meanwhile or during this forward movement of the arm 36, theupward projection 58 thereon will move forwardly and thus allow thespring 54 to move the selector finger 53 forwardly since the pin 59 onthe selector finger is then allowedto advance forwardly, and as soon asthe roller 136 on the arm 36 has moved forwardly sufficiently to al owthe bracket 49 to tilt downwardly about its pivot 50, the selectorfinger 53 will have advanced forwardly to an'extent sufiicient to causea fee'ler finger 68 on its forward end to project into a recess 67 inthe liner 66 of the mold which occupies ejecting position.

In carrying out the invention, the mold liners of different lengthswhich, as usual, are changeable to vary the length of theslot or castingcavity in theimold, are provided with recesses of difierent lengths vintheir rear edges to cooperate Wlt-ll the feeler finger 68. The left handliners of molds as com-J monly used in machines fof this class areusually of varylng lengths according to the length of the slugwhich itis desired to cast,

while the right hand liner is usually constant p in length or, in otherwords, the right hand end of the mold slot is always located at the samepoint. In F igs.1, 4 and 5, the left hand liner 66 which, in eachinstance, isv of the same length, is shown in position in the moldpositioned vertically in front of the ejector blade, which is the normalposition in which the operator would set the mold before starting themachine,this liner being shown cut away along its rear edge to form arecess 67 having a shoulder 167 at one end, while the liner shown inFig. 6 is relatively longer and it has a recess 67 in its rear edgewhich is relatively shorter than the recess 67 of the shorter liner,said recess 67 having a shoulder 167 at one end. Each of the left handliners to be used with the molds, in carrying out the present invention,contains such a recess, a group of these liners being shown in Fig. 11,the liners being of different lengths and the lengths ofthe recesses inthe rear edges thereof varying, in the present instance, inverselyaccording to the lengths of the liners, and directly according to thelengths of the mold slots produced by such liners and to the widths ofthe ejector blades which'conform therewith.

When the bracket 49 tilts downwardly due to the forward movement of theroller 136 carried by the arm 36, the feeler finger 68 on the forwardend of the selector finger 53 swings downwardly in the recess 67 or 67in the rear edge of the liner 66 until it stops against the end orshoulder 167 or 167 of the recess, it being understood that the theoperating lever 42 back hangs, to shift the forward movement of the arm36 which carries the upper projection 58 thereon forwardly in front ofthe pin 59 on the selector finger 53 allows the latter to move forwardlyto carry the feeler finger 68 into the recess in the rear edge of theliner 66 before the roller 136 disengages from and allows the bracket 49to swing downwardly about its pivot 50, so that when this downward swingof the bracket 49 takes place, the feeler finger 68 will move downwardlywhile projecting into the recess in the rear edge of the liner. Fig. 4represents the relative positions of the parts when the operating lever42 has been partially returned from its forward posi tion and the shaft23 has moved forwardly to a point where the roller 136 on the arm 36 hasdisengaged from and hence no longer supports the bracket 49. During theforward movement of the arm 36 from the position shown in Fig. 1 to thatshown in Fig. 4, the selector finger 53 advances to project the feelerfinger 68 into the recess in the rear edge of the mold liner 66, asstated, until the pin 56 fixed to the selector finger 53 abuts againstthe forward end of the slot 57 in the bracket 49, thus arresting theforward movement of the feeler linger 68 under the action of the spring54., and the downward swing of the feeler linger 68 takes place freelyin the recess in the mold liner 66 until it comes to rest on theshoulder 167 at the end of such recess, it being understood that theextent of downward swing or tilt of the bracket 49 and selector finger53 will vary in accordance. with the length or extent of the recess 67in the mold liner. This downward swing of the bracket 49 and selectorfinger 53 also brings the lower end of the pawl 62 into a positionopposite to or in front of the stepped forward end 61 on the arm 36, theheight of thelower end of the pawl 62 relatively-to the steps 61depending on the length of the recess in the rear edge of the linerwhich controls the extent of downward swing of the bracket 49 andselector finger 53. Further movement of to normal position furtheradvances the arm 36 forwardly, causing the gravity pawl 62, the lowerend of which is engaged by 'an'appropriate step on the forward end ofthe arm 36, to rock about the rear end of the stop screw 64 as afulcrum, the upper end of the pawl 62 being thereby swung rearwardly andacting through its pivot pin 63, on which the pawl selector finger 53rearwardly against the action of the spring 54.

Upon the complete return. of the operating I cu "- register wi ample in"be allowed to thus allowed the arm 36 causes then occupying theposition shown in Fig. 5. it will be apparent, from l ig'. 4, that theorward movement of the arm 36 has not cached the point where it willshift the ector blade box 31 since the lug 34-, through which theejector blade box is shifted, has not been engaged by the rear wall ofthe aperture 65 in the arm 36, and in Fig. 5, the log 3% has beenengaged by the rear wall of the aperture 65, and in carrying outtheinvention, the aperture 65 is so positioned that th lug 3% will bemerely engaged by the rear wall of said aperture when the first orlowermost step 61 is in engagement "with the pawl 62 and the arm 86 hasbeen moved forward by return of the operating lever 42 sufficiently towithdraw the teeler finger 68 from the recess 67 in the mold liner 66.

Means is provided for positioning and locking the master blade 2'8longitudinally during the ejector blade changing operation, in order toinsureproper engagement of a selected ejector blade therewith. Theconstruction shown. "for this purpose comprises a cam block 69 which ispinned or otherwise fixed to the rear end of the shaft 23 a the moldslide 1, as shown in 1, is provided.

with a vertically extending recess 70 covered 1 by a plate 71 to form avertical guide chan nel for plun er or bolt 72, the latter having arearward extension73 which carries con tact shoe, preferably in the formof a roundnose set screw 74. A stop pin 75 is lined in the side of themold slide and projects into a vertically extending recess 76 in thebolt 72 to prevent dropping of e bolt out of its guide channel 70.wardly beyond the cover plate 71 and .a spring 77 is secured to a pin 78fixed in the upper end of the bolt 72, the other end of the spring beingattached to a pin 7 9 secured The bolt 72 in the cover plate, tl "ringacting con stantly to urge the olt master blade28 of the vided with anotch 80 s lower 0 the forward wall of which is preferably inclined orbevelled as shown in 8, and the bolt 72 has a correspondingl s apedtongue 81 which is offset laterally from one side thereof so that itunderlies the notch 80 and is engageable therewith when the bolt 72 israised,

Then the shaft 23 is in its forward or normal position, the tongueSl onthe bolt 72 will be disengaged from the notch 80 in the master blade 28since the contact shoe 7 4 on said bolt will then rest on the lower face69 of the cam block 69, and the master blade 28 will then be free toreciprocate without obstruction by the bolt lVhen the shaft 23, however,is pushed to the rear, due to the swinging of the operating lever 42forwardly in order to release l e mold turning pinion 7 and permit thesetting up of a different mold on the mold wheel, the bolt '?2 be liftedb the rid-ins of the inclined or ra sod C) b c 1 v 7" i +1 face 69 orthe cam block 69 against u1e con tact shoe or screw 74 ano. the tongue81 on the bolt 72 will then be engaged in the notch 80 in the lower edgeof the master blade Such engagement of the tongue on the colt 72 withthe notch 80 in the master blade serves to lock or retain the eiectorslide 24 against forward movement whenever the operating lever 42 standsin the forward position, and the bolt 7 2 also serves as a locatingmeans for the master blade 28, since the position of the notch 80therein is such that when it registers with he bolt 72, the extension 29on the master blade 28 will lie in eXacttransverse alignment with thesimilarly shaped extension on the guide post 38 and the extension 29 onthe master blade will therefore be in exact transverse alignment withthe correspondingly shaped recesses in the rear edges of the ejectorblades 30 to insure accurate engagement therewith.

Means is preferably provided to insure the complete return of theoperating lever 42 to normal position aft-er each operation thereof,such means in the present instance comprising a tension spring 82 whichis secured at its forward end to a pin 83 on the bracket 41 attached tothe mold slide 1 and fastened at its rear end to a pin 84 which i to aplate 85, the latter being secured to the arm 36, the tension of thespring 82 acting to constantly urge the arm 36 and the shaft 23 to whichit is fixed, forwardly. This spring will insure the complete return ofthe ooeratin lever 42 to normal position in the event that the operatorshould swing the opi 1 1, 3.1 J. crating lever 42 sufiiciently to unlockthe roggle formed by it and the link but fail to complete the returnmovement of the operae lng lever to normal POSltlOIL In the modificationshown in Figs. 9 and seciu'ed' said shaft.

10, the operating lever 42 is connected di rectly to the shaft 23, thusdispensing with the link 45 used in the previously describcrconstruction. In this modification, the spring 82 performs the samefunction of urg ing the operating lever 42 back to normal positionexcept that, in the absence of the looking link used in the previouslydescribed construction, the spring 82' will always tend to return theoperating lever 42 to normal po-- sition, thus making it necessary forthe operator to hold the operating lever 42 forwardly while turning themold pinion 7 incident to the operation of changing the mold, thisarrangement having the advantage that it automatically returns theoperating lever 42 to normal position after each mold changingoperation.

in the construction shown in F 9 and '40, the pin 9 must be disengagedfrom the recess 11 in the mold wheel turning pinion 'Z'before the moldwheel 6 can be revolved to bring another mold into action, as in theprevious construction. In order that the pin 9 may be thus disengagedfrom the pinion 7 but not until the operating lever 42 has been given afull forward stroke, the levers 17 and 20 of the previously describedconstruction are replaced by levers S6 and 87. The lever 86 is pivotallyconnected at its upper end by a pin 88 to collar 89 secured to the shaft28 and the lower end of this lever is pinned or otherwise fixed to oneend of the 18. A short crank 90 is pinned or otherwise fixed to theother end of the shaft 18, it extending downwardly therefrom andcarrying a crank pin 91 which operates in a slot in the lower end of thelever 87. The

lever 87 is mounted to rock on a pivot pin 92 which is 1 :-:ed in andsupported by the arm 4 of he maclnneframe, and the upper end of thelever 8"? is pivotally connected to the clutch arm 12 which, as in thepreviously described construction, has an upwardly extending yoke wnichoperatively engages the clutch collar 10 which carries the pin 9.

In this modified construction, pulling of the operating lever 42forwardly causes the shaft 23 'to move rearwardly and such rearwardmovement of the shaft 23 swings the upper end of the lever 86rearwardly, thereby causing rotation of the shaft 18 and with it thecrank 90, both of whichare secured to Movement of the crank 90 will thenproduce a forward movement of the lower end of thelever 87 about itspivot pin 92 and the upper end of the lever 87 will therefore moverearwardly, thereby shifting the clutch arm 12 and the clutch collar 10and pin 9 rearwardly, thus disengagingthe pin 9 from the recess 11int-he pinion 7. The

the pinion 7 will be considerably slower while i the operating lever 42is being swung for wardly, and preferably and as shown, suchdisengagement of the pin 9 from therecess 11 in the pinion will not becomplete until the operating lever 42 has been moved into its fullforward position, whereupon the 11 has again been brought into register.with i the pin 9, such register of the recess 11 and pin 9 taking placewhen the next mold on.

the mold wheel has been brought into operative position. As soon as therecess 11 comes into register with the pin 9L the operating lever 42,under the action of'the spring 82, will automatically swing back tonormal position and the shaft 23 will correspondingly move forwardly,carrying with it the arm 36. which latter will bring about automaticselection of the proper ejector blade 30 in the same manner as in theconstruction previously described. The general operation of automaticejector selecting mechanism constructed as hereinbe e described is asfollows: Assuming that adjustable liners for the molds are prota-e videdin their rear edges with recesses 67 or 6'7 of different lengths whichvary in versely according; to the lengths of these liners and that theejector blade 'boi; of the ejector mechanism contains e ector blades'ofdifferent widths varying according to the clifferent lengths of the moldslots obtained by the use of the dlfierent length ad ustable liners, inorder to rotate the mold wheel to bring a different mold thereon intooperative position or to, enable mold thereon to j j .1 ,H .j:j fr I. 0erelLaced finale? m havlnb a C e lever 42 and becoming disengaged fromsaid ent length slot or casting cavity or-to enable the adjustable linerof a mold onthe mold .wheel to be changed for one of a different lengthand to automatically bring into op- A era-tion an ejector blade of aproper width to conform with the length of the slot in the meld broughtinto operative position; it is only necessary for the operator to pullthe operating lever 42 to its full forward position and to return orallow this operating lever to return to its, normal rear position.

'l he pulling forward of the operating lever 42 moves the shaft 23rearwardly, carrying h cam block 69 with it and thereby actuatne bolt 72to position the master blade .1: ejector blade shifting operation andodrithe master blade in such position and the rearward movement of theshaft 23 dud also moving'the arm 36 rearwa'rdly, the latter portion ofthe rearward movement of this arm causing it'to pickup the lug 34'and tomove such lug rearwardly, thereby causing the bars 32 of the ejectormechanism to be drawn rearwardly and causing the ribs 35 on said bars'actine; on the ejectorblade box 31 to' shift said box laterally to oneof its extreme lateral positions where, for example, the widejectorblade 3O therein is brought into register or longitudinal alignment andinto operative engagement with the master blade 28. he latter-portion.of such rearward movement of the arm, 36'also causes the roller 136thereon to engage the cam face 137 on the vertically swingable bracket49, cans-'' ing the latter,togetl1er with the selector finper 53 toswing upwardly into the position shown in Fig.- 1 and the 'final'portionof the rearward movement of the arm 36 will cause "the upwardlyprojecting portion 58 thereon to engage the pinv 59 on the selectorfinger 53 and to slide the latterrearwardly against the action of thespring 54 into the position shown in Fig. 1. the .feel'er finger 68 onthe forward end bf the selector finger being then retracted from therecess 67in the rear edge of thead ustable mold liner; 6-6 so that thisJ feeler finger will not obstruct rotation of the mold wheel 6. Theforward swing of the operating lever 42 also acts tounlock the moldwheel turningpinion 7 from its drivinn shaft 8'so that the mold wheelfnay be turned. to effect the mold changing or alterinn operation, theclutch collar 10 in Figs. f

l to 8.,'incll.isive-,-beinp; shifted rearwardly to disengage the-pin8thereon from the recess 11 in the pinion 7 during the latterportion ofthe forward swing" of the operating lever 42. due to the engagement ofthe set screw 21 moving rearwardly with the shaft 23 with the upper endof he lever 20, and the clutch collarlO Figs; 9 and lO'beingprogressively withdrawn from the recess-11. in the pinion? during theforward swine of the operating cannot bestarted inadvertently intooperation by the starting handle46, and since the mold wheel turningpinion 7 is disconnected from its driving shaft 8, the mold wheel mayberotated to bring another mold thereon into operative positionor to bringa mold thereon from the normal vertical or ejecting position to theupper horizontal or. casting position for replacement by another mold orfor changin of the length of the adjustable liner therein after whichthe mold wheelmay be rotated to return theniold to the normal ejectingposition.

After the desired mold change has been made, the operating lever 42 isswung rearwardly or allowed toswingrearwardly un der the action of thetension spring 82, the

shaft 23 then moving forwardly. The ini tial part of the forwardmovement of the shaft 23 causes the arm 36 carried by it to also moveforwardly, thereby causing the upward extension 58 on this arm to movefor is of the greatest length, so that the lowwardly from the pin 59 andalso causing the roller 136 to move from aposition beneath the cam face137 on the bracket 49,in consequence we of which the selector finger 53will move forwardly under the tension of the spring 54 and the bracket49 will swing downwardly by gravity about its pivot 50, thus moving thefeeler finger 68 forwardly into the recess 67in the rear'edge of theadjust able liner 66 of the mold which is then in ejecting position, andcausing the feeler linger 68 to descend until it comes to rest on theshoulder or inner end 167 of the mold liner, as shown in Fig. 4.Duringthis part of the forward movement of the arm 68, the lug 34-will-have a lost motion 1n the aperture in the arm 36, the forward edgeof this aperture advancing from a position in contact with this lug asshown in Fig. 1 to a position removed forwardly therefrom as shown inFig. 4. The length of the recess 67 in the mold liner 66 determines theextent of down-- ward swing of the selector finger 53' and bracket 49.For example, the liner-66 shown in 4 is of the shortest length so thatthe mold slot will be of greatest length, requiring the widest ejectorblade, and the recess or end of the gravity pawl 62 depending from theselector finger 53 will descend to a position opposite to the lowest andforemost step 61on the forwardextension 60 of the arm 36. In this case,as the forward movement of the arm 36 continues, the pawl 62, the lowerend of which is engaged with the lowermost and foremost step 61, will beroclzedabout the stop screw 64 as a fulcrum, causing its upper end toswing rearwardly and actlng through its pivot 63 to shift the selectorfinger 53 rearwardly, against the action of the spring 54, until the pin56 stops against-the rear end of the slot 57 in the bracket 49, thefeeler finger 68 being then withdrawn rearwardly from the recess 67 inthe mold liner 66 as shown in Fig. 5 and the forward advance of the arm36 being arrested at the moment the rear edge of the aper ure 65 in thearm 36 contacts with the lug 34. Since the lug 34 is thus not shifted toconform with the 'of the mold liner so forwardly, the eject-or blade box31 will remainat the extreme lateral positionwhich presents the widest eector blade 30 therein .in register with the master blade :28, itbecoming attached thereto by the engageni ,i i of the extension 29 ofthe master blade with the correspondingly shaped recess in the rear edgeof such ejector blade. During the initial part of the forward mo shaft23 under the tension of g and while the arm 36 is moving idly withrespect to the lug 34 from the position shown in Fig. 1 tothat shown in4, the bolt 72 descends. out of locking engagement with the master blade28, the contact screw 74- then riding downwardly to the lower cam face(3i, and the forward movement ofthe shaft 23 re-loclrs the pinion 7tovits driving shaft. 8, either during the early por ion of the for wardmovement of said shaft by the retraclion of the set screw. 21 from thelever 20 in Figs; 1 to 8, inclusive, or by turning of the pinion 7 tobring the recess 11 therein into register with the pin 9 in theconstruction shown in Figs. 9 and 10. Since an e ector blade of properwidth for the mold in operative position has been thus brought intoposition to be operated by the maste blade28, the machine may be started1 pulling forward the usual starting handle If the adjustable mold liner66in the mold brought into operative position is relatively longer thanin the exam ale describe' ing a relatively shorter slot ca ity in themold'and requiringa vielatiwaly narrower ejector blade, the operation isthe sameas above described with exception that the relatively shorterrecess 67 in the rear edge of such longer mold liner will arrest thedownwardswing of the braclie; 49'

and the selector finger at a. relatively high er level so that the lowerend of the pawl will be opposite to one of the intermediate withoutobstruction I hereby.

In bringing a mold into use which has an ad ustable liner 66 of maximumlength forming a slot 1n the mold of minnnum length and the oblique ribsch -e or its parts and requiring the use of the narrowest ejector blade,it will be understood that the recess in the rear edge of such linerwill be of-minimum length it will arrest the downward swing of theselector finger 53 at the highest level so that the lower end of thepawl will be engaged by the uppermost and rear most step 51 and hencethe arm 36 will be permitmd to move forwardly to its maximum or fulliitent, moving the lug 3% forwardly a corresponding distance and therebyshifting the ejector blade box 31 lateral y LO its extreme positionwhere the narrowest e ector blade 50 registers with the master blade 28,as shownin Fig. 8. By graduating the steps 61 and the recesses 67 in therear edges of the adjustable mold linersto conform with the varyingwidths of the ejector blades in the ejector blade box, it will beunderstood that an e ector blade of the proper width is brought of theslot or casting cavity in the mold in operative position.

' Since the bringing of another mold already on the mold Wheel intooperative or active position, or the removal of a mold from the moldwheel and substitution of another mold or the changing of the adjustableliner of a mold on the mold wheel all require rotation of the mold wheelto remove the mold previ ously in use from its normal vertical positione ecting mechamsm, and such in front of the v rotation of the moldwheel. cannot take place until after the mold wheel turning pinion hasbeen unlocked o unclutchcd from its operating shaft, which latter oper;.ion does not talre place until the operating lever has been operated ordrawn forwardly to substantially its full extent, and such fulloperation of the operating lever insures proper and complete operationof the ejectorblade selecting mechanism, the selection of an ejectorblade of proper width to conform with the length of the slotin the moldbrought into use is always insured. The control of the starting handleof the machine bythe ejector blade selecting mechanism prevents startingof the machine while the operating lever for t 196]. ector selectingmechanism is pulled. forwardly from its normal operative result from theuse of an ejector bladeof improper width to conform with the lengthauto- .matically into use to conform with the length rotatable in. d

of the slot or casting cavity in the mold wheneve'ra different mold isbrought into use or a change is otherwise made in the length of the moldslot, but also provides means for automatically selecting and bringingan ejector blade of the proper width into'operative position whenever achange is madein the length ofthe mold slot in whichthe slugs are to becast, thereby greatly ass1sting the operator and saving time in settingthe machine to opcrate with a mold of changed length.
